Mr Abdullah was one of 17 people who signed the petition following a patient’s complaint about a nurse. He also wrote a letter in which denied his colleague was ‘lazy’ and ‘unfriendly’, as she was claimed to be.

He was dismissed for gross misconduct on 21 December, and was treated for depression and suicidal thoughts at St Charles Hospital in Ladbroke Grove while awaiting his appeal.

He was under close observation, but was nevertheless allowed to leave the hospital two days before his hearing. Less than four hours later, at 3am, his charred body was discovered outside Kensington Palace.
